Raptor rs 140 (15/16) vs Raptor rs 130 (14/15)

[Eiszapfen]

Hello,

I currently have the new Head raptor rs 140 at home. I'm wondering if Head made any major changes compared to the raptor rs 130 of last season? I couldn't find any numbers about ramp angle or forward lean yet...
I also realized there's currently only one hole for one flex screw (120). Can I drill the other two holes by myself? How did you do this?

Kind regards!
